Is anyone out there running a 35” tires and how has it affected your fuel mileage I and currently running a 33x12.50x20 and 6” inch lift with the 3.55 gears and I’m getting 23-24 on the highway I was wanting to get 35’s just wondering how much it will affect my mileage

I have 35x12's on the factory 20" wheels and it has certainly affected my mileage. The truck is stock other than the Fox 2.0 level kit and 35" tires. When the truck was bone stock it was fairly easy to get 23-24mpg. my current situation always ends up being around 18-19. That said, I've heard other folks say they are getting 25-26 with about the same setup. Maybe its the Minnesota fuel, don't know but I'm looking for ways to get some MPG back.
